Lichens are organisms widely used as bioindicators of air quality. Due to the sensitivity of these organisms to atmospheric pollutants, in highly polluted environments, only the most resistant species predominate or even become extinct. In this work, the concentration of lichens on trees in the city of Paranaguá was evaluated to compare the air quality of the port and commercial area with the air quality of the residential region. We evaluated ninety trees distributed throughout the city, where we observed that both the concentration of lichens and the variety of species are higher in residential areas than in port areas, probably due to the better air quality in the residential area of Paranaguá.

Land use is the utilization and reordering of land cover for human comfort. This process disrupts the pristine state of the environment reducing the quality of environmental receptors like water, air, vegetation etc. Air pollution is introduced into the environment as a result of anthropogenic activities from commercial, industrial and residential areas. These activities are burning of fossil fuels for power generation, transport of goods and services, valorization of raw materials into finished products, bush burning, use of gas cookers, generators and electric stove etc. The introduction of pollutants into the planetary layer of the atmosphere has impacted negatively on the quality of the environment posing threat to humans and the survival of the ecosystem. In Lagos metropolis, commercial activities and high population densities have caused elevated levels of pollution in the city. This study aimed to investigate the spatial distribution of pollutant in Lagos metropolis with a view to revealing the marked spatial/temporal difference in pollutants levels over residential, commercial and industrial land uses. Commercial and industrial land uses revealed higher levels of pollutants than the residential areas. Pearson product moment correlation coefficients revealed strong positive relationship between land use and air quality in the city.

Modernisation of apartment houses is a particularly relevant issue both in Lithuania and many other countries. To make it more efficient, the modernisation of apartment houses must be integrated–an entire block or residential area must be renovated and the principles of sustainable development must be followed. This article dwells on the issues related to retrofit planning in residential blocks/areas and analyses the condition of apartment houses and their environment. The article also proposes strategies for retrofit of residential areas with apartment houses. The strategies aim to improve the living standards and the quality of environment, to cut energy consumption and Co2 emissions, to maintain mixed social structure, to integrate new buildings into the existing environment in a sustainable manner, to develop an urban centre of a residential area as a functioning part of the city, to develop democratic planning and to seek close cooperation of modernisation partners. The scenarios based on relevant strategies must define the measures of retrofit, their priority and their potential effect. Santrauka Daugiabučių gyvenamųjų namų modernizavimas šiuo metu yra ypač aktuali problema ne tik Lietuvoje, betir daugelyje kitų šalių. Kad modernizavimas būtų efektyvesnis, daugiabučius reikia atnaujinti kompleksiškai, modernizuojant visą kvartalą, rajoną, vadovaujantis darniosios plėtros principais. Šiame straipsnyje aptariamos gyvenamųjų kvartalų, rajonų atnaujinimo planavimo problemos, analizuojama daugiabučių ir jų aplinkos būklė. Siūlomos daugiabučių rajonų atnaujinimo strategijos, kuriomis siekiama: gerinti gyvenimo standartus ir aplinkos kokybę, mažinti energijos suvartojimą ir CO2 emisiją, išlaikyti mišrią socialinę struktūrą, darnų naujų pastatų integravimą į jau egzistuojančią aplinką, plėtoti miesto centro kaip funkcionalios miesto dalies daugiabučių namų rajone sukūrimą, demokratinį planavimą bei prie modernizavimo prisidedančių partnerių glaudų bendradarbiavimą. Scenarijai, grindžiami atitinkamomis strategijomis, privalo apibrėžti renovacijos darbų priemones, jų įgyvendinimo prioretiškumą ir būsimus poveikius.

The air quality of modern cities is considered an important factor for the quality of life of humans and therefore is being safeguarded by various international organizations, concentrating on the mass concentration of particulate matter (PM) with an aerodynamic diameter less than 10, 2.5 and 1 μm. However, the different physical and anthropogenic processes and activities within the city contribute to the rise of fine (<1 μm) and coarse (>1 μm) particles, directly impacting human health and the environment. In order to monitor certain natural and anthropogenic events, suspecting their significant contribution to PM concentrations, seven different events taking place on the coastal front of the city of Limassol (Cyprus) were on-site monitored using a portable PM instrument; these included both natural (e.g., dust event) and anthropogenic (e.g., cement factory, meat festival, tall building construction, tire factory, traffic jam, dust road) emissions taking place in spring and summer periods. The violations of the limits that were noticed were attributed mainly to the various anthropogenic activities taking place on-site, revealing once more the need for further research and continuous monitoring of air quality.

Transboundary air pollution (TAP) and local air pollution (LAP) influence the air quality of urban areas. Fukuoka, located on the west side of Japan and affected by TAP from the Asian continent, is a unique example for understanding the contribution of LAP and TAP. Gaseous species and particulate matter (PM) were measured for approximately three weeks in Fukuoka in the winter of 2018. We classified two distinctive periods, LAP and TAP, based on wind speed. The classification was supported by variations in the concentration of gaseous species and by backward trajectories. Most air pollutants, including NOx and PM, were high in the LAP period and low in the TAP period. However, ozone was the exception. Therefore, our findings suggest that reducing local emissions is necessary. Ozone was higher in the TAP period, and the variation in ozone concentration was relatively small, indicating that ozone was produced outside of the city and transported to Fukuoka. Thus, air pollutants must also be reduced at a regional scale, including in China.

This study was conducted to assess the building coverage and environmental quality of residential area in Nkpor Uno Idemili North L.G, Nigeria. The study employed a descriptive survey design to find out level of compliance of buildings to planning regulations. One hundred and eighty (180) were interviewed using a modified instrument (questionnaire). The data collected were coded into SPSS and analyzed with descriptive statistics. The results showed that 72(40%) reported inadequate setback as a major effect of over built buildings, 55(30.6%) reported inadequate free air space, 37(20.6%) said inadequate ventilation and lighting. Also, the nature of drainage system provided in residential areas; 76(42.2%) has no drainage system, 70(38.9%) has close drainage system. The building coverage of residential houses in the study area; 60(33.3%) has their building falls under 51-75% for over built, 48(26.7%) has their building falls under 76-100% for overbuilt. For the factors influencing the percentage of area built upon, 57(31.7%) has greed and no money to acquire a large plot of land, 47(26.0%) has no land space to built their desirable house. Then, non adherence to provision of adequate ventilation and lighting in the residential houses in the study area affects the dwellers’ health and such factors can promote communicable diseases. In conclusion, it was observed that the compliance rate was not encouraging because the planning regulations recorded very low compliance as include set–back from property boundaries; inadequate free air space; lost of aesthetic values, and inadequate ventilation and lighting. Therefore, government should embark on enforcement of land use plan, and strategic plans for various towns and villages to accommodate its utilities and facilities.

In Latvia, after restoration of independence on May 4, 1990, the economy was restructured. In Liepaja, without analyzing city's historical planning and not finding successful solutions for inhabitants, many factories closed down. Not getting to know with the Detailed Plan of the residential area "Green Grove", professionally developed by architect Irena Rubauska, and lobbying individual interests, specialists of "Group 93" Ltd. produced a new territorial plan for Liepaja. In 2007, Latvian in prison reform was started. The first prison was decided to build in the residential area "Green Grove". The object of research – Liepaja residential district "Green Grove". Research problem – functional and structural changes of "Green Grove" are implemented without performing the analysis of earlier urban development concepts and do not ensure harmonious development of inhabitants’ living environment. The goal of research – analyze the influence of Liepaja Economic Zone and city development strategies on quality of inhabitants’ living conditions in residential areas of "Green Grove". Main methods applied – this study is based on analysis of archive documents, projects, cartographic materials of urban planning, study of published literature and inspection of buildings in nature.

RESUMO:Esse ensaio contextualiza a produção de sal marinho no Brasil e sua localização no período colonial, próximo aos povoados da costa nordestina para investigar a inserção das antigas salinas nas cidades. As salinas artesanais foram transformadas em áreas residenciais, mas dada as condições ambientais de algumas áreas, ainda, existe a oportunidade de integrá-las na condição de infraestrutura urbana verde resgatando, também, sua memória cultural. Assim, se faz uma evolução das áreas ocupadas por salinas e dos métodos de produção, quando se situa às condições mais propícias a produção do sal, bem como, seus conflitos com a proteção dos ecossistemas de manguezais das planícies flúvio- marítimas. Se discute a capacidade de regeneração desses ecossistemas em áreas de salinas desativadas e sua oportunidade de instalação de parques urbanos em cidades desprovidas de verde. O caso de estudo ocorre na área das antigas Salinas Diogo, que hoje é o Parque do rio Cocó na cidade de Fortaleza. Como resultado se destaca a integração das áreas de salinas à cidade com grande ganho de qualidade de vida urbana, mas que, por outro lado, as salinas não comparecem na imagem coletiva urbana o que remete a um estudo de proteção da memória da paisagemcultural.  RESUMEN:Este ensayo contextualiza la producción de sal marina en Brasil y su ubicación en el período colonial, cerca de las aldeas de la costa noreste para investigar la inserción de antiguas salinas en las ciudades. Las salinas artesanales se transformaron en áreas residenciales, pero dadas las condiciones ambientales de algunas áreas, todavía existe la oportunidad de integrarlas en la condición de infraestructura urbana verde, también rescatando su memoria cultural. Las áreas ocupadas por solución salina y los métodos de producción evolucionan cuando se crean las condiciones más favorables para la producción de sal, así como sus conflictos con la protección de los ecosistemas de manglar de las llanuras marítimas fluviales. Se discute la capacidad regenerativa de estos ecosistemas en áreas de salinas desactivadas y su oportunidad de instalar parques urbanos. El estudio de caso ocurre en el área del antiguo Salinas Diogo, que hoy es el Parque del Río Cocó. Como resultado, se destaca la integración de las áreas salinas en la ciudad, con una gran ganancia en la calidad de vida urbana, pero las soluciones salinas no aparecen en la imagen colectiva urbana, lo que lleva a un estudio de protección de la memoria del paisajecultural.ABSTRACT:This essay contextualizes the production of sea salt in Brazil and its location in the colonial period, close to the northeastern coast villages to investigate the insertion of old salt flats in cities. The artisanal salt extraction were transformed into residential areas, but given the environmental conditions of some areas, there is still the opportunity to integrate them in the city, also rescuing their cultural memory. Occupied areas and production methods are evolved when the conditions most favorable to salt production, as well as their conflicts with the protection of mangrove ecosystems of the river-maritime plains are made. The regenerative capacity of these ecosystems in areas of deactivated salt production and their opportunity to install urban parks in cities are discussed. The case study occurs in the area of the former Salinas Diogo, which today is the Cocó River Park. As a result, the integration of saline areas into the city stands out, with a great gain in urban quality of life, but, on the other hand, salt production do not appear in the urban collective image, which leads to a study of protection of the memory of the culturallandscape.

PurposeResidential satisfaction can be viewed as a part of life satisfaction. There are many studies related to the relationship between residents’ satisfaction with their environments and the quality of those environments. The purpose of this paper is to examine how this satisfaction differs according to the type of residential environment.Design/methodology/approachIt is based on empirical data on the quality of life in the different residential environments of the Istanbul Metropolitan Area. The primary source of information was a household survey.FindingsIn an attempt to find solutions to problems with the quality of residential environments, the data were analyzed through several variables related to the subjective perceptions of residential satisfaction. According to the results of the research, residents living in planned neighborhoods in the city are more satisfied than those living in unplanned neighborhoods. The residents who live in the planned sections of the city are satisfied with the attractiveness and accessibility of their neighborhoods, while those who live in unplanned sections of the city are satisfied with their level of attachment to their neighborhoods.Practical implicationsThe study was designed to produce baseline data so that future changes in residential conditions as perceived by the residents of Istanbul could be monitored to support decisions for residential areas.Originality/valueComparative case studies, especially on planned vs unplanned environments, are relatively limited in number. Therefore, there is a need for new researches examining differences between different residential settings within cities. This study adds value to the field of comparative studies on residential environments.
